We're setting up a WPMS install that will use the domain mapping plugin to point a custom TLD to each site. Enabling SSL for each domain will be a requirement.
We're on Cloudways which can only support 1 cert per app (the WPMS install in this case) and Let's Encrypt certs max out at 100 domains per cert. Since we'd need SSL for www and non-www version of each domain this would max us out at 50 sites with mapped domains, which we'd blow through quite quickly. ServerPilot seems to suffer from the same limitation.
Does anyone know of a workaround for pointing more than 50 SSL-enabled domains at a multisite install? For example if we could create dummy apps, add the domains/certs there, and somehow proxy the traffic through them to the main WPMS install?
I'm fully aware we can tackle with Cloudflare but would prefer to avoid having to tell every customer to set up a CF account, point their DNS to it, etc. I want the streamlined nature of "Point your A record at our IP and you're good to go."
Ideally I'd love to have a solution that stays within Cloudways, but I'm also open to third-party addon solutions or other webhosts entirely if, on the customer end, they'd only be required to point an A record at a specific IP.
Thanks for any insight!
